Tajriba natijalarini hisoblash.

1. V(H₂) = V₁(oxir.) –V₁(bosh.), - formuladan foydalanib ajralgan vodorod hajmini hisoblang.

2.P(H₂)=P(atm)-P(H₂O) – formuladan foydalanib vodorodning partsial bosimini toping.

3.P_oV_o/T_o= P(H₂)V(H₂)/T V_o=[ P(H₂) _*T_o/ P_oT] _* V(H₂) – formuladan foydalanib vodorod hajmini normal sharoitga keltiring.

4.Quyidagi tenglama bo‘yicha : m(H₂)= M(H₂) V_o(H₂)/ V_m ajralgan vodorodning massasini hisoblang.

5.Ekvivalent qonuniga asoslanib metall ekvivalentining molyar massasini aniqlang:

a) m(Me) /m(H₂)=Ekv(Me) /Ekv(H);

vodorod massasi bo‘yicha Ekv (metall)= m(Me) _* Ekv (H)/ m(H₂)

b) m(Me)/V_o(H₂)= Ekv Me)/ V_ekv(H);

vodorod hajmi bo‘yicha Ekv (metall)= m(Me) _* V_ekv (H)/V_o(H₂).

6.Tajribaning absolyut va nisbiy xatolarini aniqlang.
